DobromirBG87 Posted June 8, 2020 Report Share Posted June 8, 2020 Hi guys, I am having issues starting my ls1 with link g4+ atom and I cannot figure out what is going on. Sensors are wired correctly and when hit f12 it shows signal but won't sync so I guess until it syncs I won't be able to fire it up ? Trigger setup is ls1 3-12 which was the setup anoter engine before this ine used to work with but this one just refuse to start...I think they are hall sensors and provided sensors with 12v.

Adamw Posted June 8, 2020 Report Share Posted June 8, 2020 About 90% of LS1's use the 5-10 triggermode, so I would try changing to that first. Quote Link to comment Share on other sites More sharing options...
DobromirBG87 Posted June 9, 2020 Author Report Share Posted June 9, 2020 Hi Adamw, Will try this today however what about trigger edges ? Should they be failing or rising and also the trigger setup? Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 9, 2020 Report Share Posted June 9, 2020 Rising on both. Trigger offset Im not 100% sure, but likely around zero. Quote Link to comment Share on other sites More sharing options...
DobromirBG87 Posted June 9, 2020 Author Report Share Posted June 9, 2020 Trying now and nothing...signal from both sensorssensors is present but won't sync... Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 9, 2020 Report Share Posted June 9, 2020 Can you do a short log of it cranking. Attach a copy of your tune too.

DobromirBG87 Posted June 11, 2020 Author Report Share Posted June 11, 2020 Hi Adamw, I am attaching the map i am using and log from cranking the car. Log crank trigger issues 2020-06-11.llg LS1 e36.pclr Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 11, 2020 Report Share Posted June 11, 2020 You are going to have to get an oscilloscope on it to find out why the ecu is not happy about the signal it is receiving. Quote Link to comment Share on other sites More sharing options...
DobromirBG87 Posted June 16, 2020 Author Report Share Posted June 16, 2020 I am ashamed to say that but the car was out of fuel...put 15ltr in the tank started right away. Quote Link to comment Share on other sites More sharing options...

No that wasnt it. The log you attached earlier shows no RPM when cranking, so the ECU is not happy with the trigger signal it was receiving.

DobromirBG87 Posted June 17, 2020 Author Report Share Posted June 17, 2020 Well, yes as the trigger was 3-12, changed to 5-10 rpm came and started right away Quote Link to comment Share on other sites More sharing options...
DobromirBG87 Posted August 12, 2020 Author Report Share Posted August 12, 2020 Hi guys, back to the drawing board.. i blew the LS1 and put in new LS1 with LS3 crank and new Link Xtreme ECU and now i cannot start it. I think LS3 have 60-2 trigger wheel but not sure about the cam. All is the same like wiring and sensors. Strangely enough when i try to see scope reading it is only straight line both trigger one and 2. Did someone came across such issue ?

Adamw Posted August 12, 2020 Report Share Posted August 12, 2020 Do you have the matching 58X sensors fitted (grey plug)? The cam and crank sensors on the LS3 58X engines are 5V where as the common LS1 24X sensors were 8-12V. The cam sensor pinout is also reversed on the 58X engines. Pinouts are in the help file section: Wiring Information > Input Signal Wiring > Trigger Inputs > Specific Trigger Applications > GM LS...

DobromirBG87 Posted August 13, 2020 Author Report Share Posted August 13, 2020 Hi Adamw, Sensors should be from the ls1 or at least I guess so need to confirm this however why the scope function bugs when I try to use it ? Can this be from low battery ? When I use it the whole program stall and when un freeze it only shows straight lines... Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 13, 2020 Report Share Posted August 13, 2020 The scope shows flat lines because this is what it is receiving from the cam and crank sensors - nothing. You probably have no trigger 1 signal because you have the wrong sensor. If your crank shaft has the 58X trigger wheel on it then you will need the matching 58X sensor, the 24X sensor will only work with the old double row 24T wheels. The 58X sensor are all grey plastic as far as I know. The 24X sensors are black plastic. You probably have no trigger 2 signal because you have either the wrong sensor or you havent changed the wiring to match the different pinout.

DobromirBG87 Posted August 13, 2020 Author Report Share Posted August 13, 2020 Hi Adamw, I am a bit confused. So no chance to read the 58x with the ls1 24x crank sensor ? Aren't they both hall effect ? I mean only with changing the trigger settings won't make difference ? I guess I neex to take crank sensor from ls3 then. The cam is ls1 layout so I guess the sensor will be correct. Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 13, 2020 Report Share Posted August 13, 2020 The LS1 (24X) uses two trigger wheels stacked side by side with two different tooth patterns on each. The 24X sensor is basically two sensors side by side in the same body that combines the signals from the two wheels into a single output. It will not work with the 58X wheel which is just a single row wheel and requires a single row sensor. Quote Link to comment Share on other sites More sharing options...
DobromirBG87 Posted August 13, 2020 Author Report Share Posted August 13, 2020 So no chance runing ls3 with ls1 crank sensor ? Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 13, 2020 Report Share Posted August 13, 2020 Yes, you could remove the crankshaft and fit the 24X trigger wheels on to it if you really wanted to keep the 24X sensor, but most people would say it is easier to just swap the sensor.

DobromirBG87 Posted August 13, 2020 Author Report Share Posted August 13, 2020 Swapped the sensor but yet again no rpm. The only way I get stable rpm is when I use multitooth 60-2 hall effect both triggers with pull ups and on trigger 2 cam level sync but no readings in scope and doing 120-30 on cranking...

Adamw Posted August 13, 2020 Report Share Posted August 13, 2020 If you are getting RPM in missing tooth mode then it suggests the crank sensor is at least working. Are you clicking the capture button on the trigger scope when the engine is cranking? Quote Link to comment Share on other sites More sharing options...
DobromirBG87 Posted August 14, 2020 Author Report Share Posted August 14, 2020 Ywa but the program stall and when unfreeze it shows straight lines. Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 14, 2020 Report Share Posted August 14, 2020 It is normal for the software to freeze for a second on a slow laptop while the triggerscope is recording. Can you do a video with your phone or something so I can see what you are doing and what you mean. Quote Link to comment Share on other sites More sharing options...
DobromirBG87 Posted August 15, 2020 Author Report Share Posted August 15, 2020 Well when I hit capture and,crank the car the,whole screen freezes. After a,minute it un,freezes. However the,car started with the ls1 sensor with,the ls3 crank wheel. Not sure how. Will share update shortly. Quote Link to comment Share on other sites More sharing options...
